6. Externally-observable properties
Composed discrete program:
| Property | Observable condition |
|---|---|
| R5 — Composed order-structured program | Executable composed discrete program observably composing orders; in the model-as-map layered embodiment, observably executing as order-governed traversal under the domain model as a navigational map with a subordinate specification override layer |
| R5a — Composition witness present and chainable | The composition witness carries constituent representation identities, formation witness per constituent (replay or justification record), composition locus records, composed-program content hash, emergent-output attribution records, and use-verification records for traversals and evaluations; it chains from constituent IR witness links through the composition step |
| R5a2 — Use-verification records present | Submit a traversal or evaluation over a composed program; confirm the composition witness carries a use-verification record from which the path taken through the order-governed structure is independently re-derivable; absence of use-verification records is a structural incompleteness |
| R5b — Reuse without limitation | Single composed discrete program consumed by two or more distinct consumers without re-derivation; consumer verification proceeds against the composition witness without trust in the composing deployment |
| R5c — Override-layer conflicts recorded in Field 6 | Where the specification override layer conflicts with a governing-specification conformance predicate, a falsifier annotation is present in Field 6 with condition subtype override-conflict; no suppression without recording is admitted |
| R5d — Data-source-alone formation | Where inputs are a data source alone, formation proceeds by semantic analysis of the source’s tables, collections, or schemas and data sampling; observe that the resulting representation is order-typed and carries a recomputation witness traceable to the source’s schema, keys, constraints, or sampled content; emergent-regime output is order-typed and witness-bound to the observations that produced it |
| R5e — Formation-method independence / witness kind follows method | Where formation employs an interpretive or non-deterministic method, the composition witness carries a justification record; where deterministic, a replay record; observe that the witness kind matches the formation method and that the order-governed, witness-bound result is produced regardless of formation method |
| R5f — Probabilistic and hybrid modes governed | Where an order or representation is probabilistic or hybrid, observe that the order-shape contract and composition witness apply: a probabilistic composition carries a recomputation witness from which the posterior or output is re-derivable under the declared update procedure; probabilistic mode is not a separate architecture |
Model-as-map layered architecture:
| Property | Observable condition |
|---|---|
| R5-map — Traversal witness present per step | Each traversal step in a model-as-map deployment carries an observable traversal witness record: model version identity, entry and exit orders, walk rule identity, and override-layer contribution; no-override is explicitly declared where the override layer contributes nothing |
| R5-map-b — Independent re-derivability of traversal | An independent inspector re-derives each traversal step from the declared model version and walk rule; a step whose outcome cannot be re-derived from those artifacts is observably non-conforming |
Cross-model composition:
| Property | Observable condition |
|---|---|
| R8 — Cross-model composition by order | Composition of representations from distinct domain models proceeds at shared order identities determined by shape identity, not label match; cross-model higher-order outputs are attributed to declared cross-model orders with registered derivation rules |
| R8a — Distinct order identities not equated | Attempting to compose representations at distinct order identities without a registered cross-domain typed interface (§02c §3) is refused with a structural violation record; no implicit equivalence between distinct order identities is admitted |
| R8b — Model-pair compatibility record verified | The model-pair compatibility record in the composition witness is independently verifiable: inspector retrieves both model versions and confirms shared order-shape specifications are identical; a record that fails this verification is observably a composition defect |
| R8c — Modality-agnostic combinatorial order analysis | Where cross-model order composition involves non-discrete representations (probabilistic, embedding-based, neural), observe that the per-order common structure, shape-identity sameness criterion, and composition witness obligations apply; a non-discrete cross-model composition that omits the per-order common structure or composition witness is observably non-conforming and not a distinct architecture |
| R7 — Order-attributed emergent output | Emergent higher-order outputs from cross-model composition are order-typed and re-derivable from their source orders and derivation rules; an emergent output not attributable to a declared cross-model order is returned as a typed gap referral with locus domain model |
Subject-directed determinations:
| Property | Observable condition |
|---|---|
| R9 — Subject-directed determination identifying the responsible order | Finding is order-typed, audit-bound, re-derivable, and identifies the responsible order — not a black-box score with post-hoc explanation; a finding without order attribution is a typed gap referral, not a determination |
| R9a — Responsible-order attribution survives verification | An independent inspector re-derives the finding from the declared order-typed evidence and derivation trace; a finding that does not survive this re-derivation is observably a false grounding, reportable as a conformance defect at Field 4 |
| R9b — Reflexive artifacts order-typed and bounded | Triage decisions, cache-hit determinations, and self-modification assessments carry responsible-order attributions and are independently re-derivable; ill-typed self-modifications are refused at the modification gate with a typed gap referral identifying the violated order constraint |
| R10 — Reflexive artifacts re-derivable; self-modification order-bounded | Triage decision or cache hit re-derives under the orders; ill-typed self-modification is rejected with a structural diagnostic |
